TDK-Lambda has released a new range of AC-DC external power
supplies with models rated from 62 to 80 watts that are EISA and CEC Level IV
and V compliant. The DT62-C & DT80-C series operate with a universal AC
input of 90 to 264 VAC (47 to 63 Hz). The DT80-C models include PFC. Typical
operating efficiencies are greater than 85%. Available output voltages include 9,
12, 15, 18, and 24 V.
These external power supplies are packaged in compact,
insulated, and lightweight enclosures that measure 2.71 in. wide by 5.2 in.
long by only 1.57 in. high and are convection cooled (no fans needed). The
operating temperature range is 0 to 40°C at full load (derate linearly to 50%
load at 60°C). All models are fully isolated (3 kVAC, input to output) and units
from 12 through 24 V are California Energy Commission (CEC) and Energy
Independence Act of 2007 (EISA) Level IV compliant. Plus, some models with
output voltages of 15, 18, and 24 V are EISA and CEC Level V compliant.
These energy-saving supplies include overvoltage and
short-circuit protections and the Off/No-Load standby-power-consumption is less
than 0.50 watt, as required by the green energy initiatives. In addition, these
supplies include UL/EN/IEC60950-1 international safety agency certifications
and meet EN55022-B and FCC Class B conducted and radiated EMI standards.
